Abstract
A simple process of 50% cold-rolled and annealed at different temperatures and times to obtain ultrafine-grained structured low-carbon steel with superior mechanical properties is utilized in this investigation. The microstructure evolves from bulky austenite to lathy martensite and then ultrafine ferrite grain with nanocarbide particles. Recovery occurs in the specimen annealed at about \(500\,{^{\circ }}\)C and 30 min, while recrystallization happens in the specimen annealed at \(550\,{^{\circ }}\)C and 30 min. The optimal balance between the tensile strength (867 MPa) and elongation (16.7%) is obtained in the specimen annealed at \(550\,{^{\circ }}\)C and 30 min, in which the mean size of ferrite grains and nanocarbides is 330 and 55 nm, respectively. Moreover, the distribution of ferrite grain conforms to the Gaussian distribution. The recrystallization activation energy of low-carbon steel with ultrafine grain is calculated to be \(320,682\,\hbox {J}\, \hbox {mol}^{-1}\) based on the Arrhenius equation.
